Question

The peak intensity of radiation from Star Beta is 350 nm. What is the average surface temperature of Star Beta rounded to the nearest whole number?

Answer 1

You'll need to use Wien's Displacement Law:\[T=\frac{ 2.8978*10^{-3}m∙K }{ \lambda _{\max} }\]Note that the units of the constant are meter∙Kelvin, so you'll need to convert 350nm to meters.
